Electron Microscope
General
The Electron Microscope as invented by Ernst Ruska and later refined and diversified by other, is a Microscope which unlike the Light Microscope uses High speed Electrons for the creation of images by various means.
The Electron Microscope can be divided into several Sub Categories
- Transmission Electron Microscope
- Reflection Electron Microscope
- Scanning Electron Microscope
- Emission Electron Microscope
Each of these priciples has its own unique advantages and disadvantegs. For further information see the related pages.
History
The Electron Microscope was invented in 1934 by German Physascist Ernst Ruska while working for the Siemens Corperation. It evolved from Ruskas findings that a aperture can be magnified by menas of a rotationally symetrical magnetic field, while studying and desining Electron Beam Oscillographs. With the help of Engineer [Max Knoll] and [Bodo von Borries], the observation quickly resulted in a functioning proof of concept aperatus which can be considered the forefather of all electron microscope. All though crude at the time, this apperatus proved the princple discovered by Ruska to be exploitable for the creation of a Microscope.
The apperatus was later Refined numerous times, leading ultimatly to the creation of the [Siemens Elektronen Mikroskop]. This unit was later refined, fallowing World War II into the [ÜM100] Microscope. Simultaniously to the development at Siemens, the German Company AEG with subsequent help from Carl Zeiss, under the leadership of [Otto Rang] and [Hans Schluge], another first generation Microscope was developed. This Microscope subsequently evolved into the AEG Zeiss [EM8]. Unlike the Siemens counterpart, this unit opperated purely by means of the [Electrostatic Lens], where as Ruskas Microscope was based exclusivly on the [Electromagnetic Lens].
